End Notes

1Value derived from the EqP method with Region III marine values (2004a) and logKow values from Karickhoff and Long (1995b). Only logKow values between 2 and 6 were used, as suggested by the EPA (2000 g).

2Currently no marine sediment value is available. Refer to US EPA Region 3’s Freshwater Sediment Screening Benchmark table for a value.

3Threshold Effect Level.

5Consensus-based Threshold Effect Concentration.

6Original value 290ug/gOC, 1% organic concentration, value converted to 2.9ug/g dry wt = 2.9mg/kg dry wt.
